title: Selection of Medications to Prevent Stroke Among Individuals With Atrial Fibrillation : Update on Prevention of Stroke in Patients with AF.
abstract: Vitamin K antagonists have been the only available orally active anticoagulants for decades. Although effective, their numerous limitations have driven the introduction of new oral anticoagulants (NOAs) that showed effectiveness at fixed doses without the need for routine coagulation monitoring. However, the safety and efficacy observed in controlled clinical trials may be hard to translate in clinical practice. Clinical conditions as well as drug interactions may considerably impact on patient outcomes. Moreover, the inability to monitor the pharmacological activity of NOAs and the absence of any antidote in the setting of bleeding or emergent invasive procedures may limit their use. Vitamin K antagonists will be still used in many circumstances, including patients with an optimal control of the INR, with mechanical heart valves, and other indications for which these new agents have not been investigated. Nevertheless, these new agents will reduce the burden of anticoagulation management at the patient as well as Health Care level.
